What you're printing out at the end is simply the current values of your iterator, cels and fahr variables. You need to keep track of the variables during each iteration. Most likey using some containers. You would then either manually write out 4 more print statments for each iteration, or create a another for loop that would iterate through and print out the values in each container.

I just tested this program, and dutifully entered the Celsius values as prompted:
"Please enter the Celsius Degree you would like to convert: "
But it seems the input should be in Fahrenheit. Maybe the prompt message should guide the user so they know what is required of them?

Back to the array. You could use a pair of arrays, one each for F and C.
